A locking clamp groove 52 is provided at the lower part of the pressure head 5. The three-groove locking clamp is slidably connected to the locking clamp groove 52 through the guide path 51. The interior of the pressure head 5 is releasably abutted against the top end of the valve stem 8, and the bottom of the pressure head 5 is releasably elastically abutted against the valve spring seat. The left end of the fixing member 6 is slidably connected to the slide rail. In this way, the lower end of the handle 1 is hinged to the upper right side of the fixing member 6 and can rotate around the upper right side of the fixing member 6. The lower part of the handle 1 is hinged to the upper end of the swing arm 2, and the lower part of the handle 1 and the swing arm 2 rotate relative to each other. The lower part of the handle 1 is hinged to the upper end of the gas spring 4, and the handle 1 and the gas spring 4 can rotate relative to each other. The lower end of the swing arm 2 is hinged to the upper end of the movable rod 3, and the swing arm 2 can rotate around the movable rod 3. The lower end of the gas spring 4 is connected to the lower right side of the fixing member 6 to provide an installation position for the gas spring 4. The lower end of the movable rod 3 is connected to the pressure head 5, and the connection can also be released, which is convenient for installation and maintenance. The pressure head 5 is symmetrically provided with guide paths 51 on both sides, and the guide paths 51 are sliding channels for the three-groove lock clip to enter the pressure head 5. A lock clip groove 52 is provided in the bottom of the pressure head 5, and the lock clip groove 52 is located below the guide path 51. By providing the guide path 51 and the lock clip groove 52, the three-groove lock clip can be accurately fixed, so that the three-groove lock clip can be accurately dropped into the lock clip groove of the valve stem 8.

The three-slot lock clamp online repair mechanism of the present invention has the following advantages over the prior art: high repair pass rate; saving repair time; improving ergonomics, eliminating repeated moving of the cylinder head and causing strain.

[0024] The three-slot lock clip online repair mechanism of the present invention can be found in Figures 1 to 5In the related figures, on the basis of the previous technical scheme, it can also be: the pressure head 5 includes a fixed block 53, a guide rod 54, two inclined guide blocks 55, two clamping plates 56 and two shells 57, the fixed block 53 is detachably fixedly connected to the bottom end of the movable rod 3, the guide rod 54 is vertically arranged at the bottom of the fixed block 53 in the front and rear directions and is detachably fixedly connected to the bottom of the fixed block 53, the bottom center of the guide rod 54 is releasably abutted against the top of the valve stem 8, the two shells 57 are symmetrically detachably fixedly connected to the front and rear sides of the guide rod 54, and the two clamping plates 56 are symmetrically detachably fixedly connected to the front and rear sides of the guide rod 54. The bottom of the sheet 56 is arranged in an arc shape and is symmetrically arranged facing each other. The two clamping sheets 56 are symmetrically arranged between the left and right sides of the two shells 57. The two inclined guide blocks 55 are symmetrically arranged and are respectively detachably fixedly connected to the corresponding clamping sheets 56 on both sides. The bottoms of the two shells 57 and the bottoms of the two clamping sheets 56 are both releasably elastically abutted against the valve spring seat. The guide path 51 is located in the inclined guide block 55 and in the cavity formed by the clamping sheet 56 and the guide rod 54. The bottom ends of the two clamping sheets 56 are arranged oppositely and surrounded by the locking groove 52. In this way, the upper end of the fixed block 53 is detachably connected to the bottom end of the movable rod 3, thereby completing the connection between the movable rod 3 and the pressure head 5, and the fixed block 53 plays a connecting role. The guide rod 54 is arranged front and back, and the upper end of the guide rod 54 is detachably connected to the bottom end of the fixed block 53, thereby directly or indirectly connecting the inclined guide block 55, the clamping sheet 56 and the shell 57 to the guide rod 54. The bottom center of the guide rod 54 abuts against the top of the valve stem 8, and the abutment is released when the online repair is completed. By setting the guide rod 54 to be connected to the valve stem 8, the pressure head 5 can be aligned with the position of the valve stem 8, thereby improving the qualified rate of online repair. The front side of the guide rod 54 is detachably connected to the shell 57, and the rear side of the guide rod 54 is detachably connected to another shell 57, wherein the two shells 57 are symmetrically arranged. The two clamping pieces 56 are symmetrically arranged left and right, a single clamping piece 56 is arranged on the left side of the two shells 57 front and back, and another clamping piece 56 is arranged on the right side of the two shells 57, thereby completing the connection between the shell 57 and the clamping piece 56. The bottom of the clamping piece 56 and the bottom of the shell 57 are formed and elastically abut against the valve spring respectively. By setting the clamping piece 56 and the shell 57, the valve spring retaining ring and the valve spring can be pressed down, and then pressed down to the position of the locking clamp groove on the valve stem 8 to stop. The left side bevel guide block 55 is detachably connected to the left side of the clamping piece 56, and the right side bevel guide block 55 is detachably connected to the right side of the clamping piece 56. The left side bevel guide block 55 and the right side bevel guide block 55 are symmetrically arranged. The upper opening of the left side guide path 51 is located at the left end of the left side bevel guide block 55, and the upper opening of the right side guide path 51 is located at the right end of the right side bevel guide block 55. The left side guide path 51 and the right side guide path 51 are symmetrically arranged. The lower part of the guide path 51 is formed by the clamping piece 56 and the guide rod 54. The guide path 51 provides a sliding channel for the three-slot lock clamp.The bottom of the clamping pieces 56 on both sides is located below the lower part of the guide rod 54, and the clamping pieces 56 on both sides are arranged in an arc shape and the arc surfaces on both sides are opposite to form a locking clamp groove 52. The locking clamp groove 52 is arranged in the same manner as the three-groove locking clamp, so that the three-groove locking clamp can fall accurately into the locking clamp groove 52, and then the three-groove locking clamp can fall accurately into the locking clamp groove on the valve stem 8. Preferably, the fixing block 53, the guide rod 54, the inclined guide port, the clamping piece 56 and the housing 57 are all connected by bolts. A further preferred technical solution is: a guide hole 541 is opened at the bottom center of the guide rod 54, and the top end of the valve stem 8 can be releasably abutted against the guide hole 541. In this way, the guide hole 541 is located at the bottom center of the guide rod 54. When the handle 1 drives the gas spring 4 and the swing arm rod 2 to move, and drives the movable rod 3 and the pressure head 5 to press downward along the direction of the valve stem 8, the top end of the valve stem 8 is inserted into the pressure head 5 and abuts against the guide hole 541. By setting the guide hole 541, the online repair mechanism can be better and stably aligned with the valve stem 8, improve the online repair qualification rate, and save repair time. A further preferred technical solution is: the left and right sides of the guide rod 54 are fixedly connected with protrusions 542, and the three-groove lock clamp is slidably connected to the protrusions 542 through the guide path 51. In this way, protrusions 542 are set on the left and right sides of the guide rod 54, and the protrusions 542 correspond to the arc grooves of the three-groove lock clamp. When the three-groove lock clamp slides along the guide path 51, the arc groove of the three-groove lock clamp is just opposite to the protrusion 542, and the three-groove lock clamp slides down along the protrusion 542 into the lock clamp groove 52. By setting the protrusion 542, the three-groove lock clamp can be accurately limited to fall into the lock clamp groove 52, and be limited in the lock clamp groove on the valve stem 8. At the same time, the protrusion 542 on the guide rod 54 can prevent the locking clip from rotating around the valve stem 8, and the two three-groove locking clips are guaranteed to fit each other without gaps, thereby improving the qualified rate of locking clip installation.

[0025] The three-slot lock clip online repair mechanism of the present invention can be found in Figures 1 to 5 In the related figures, on the basis of the previous technical solution, it can also be: the lower end of the fixing member 6 is fixedly connected to the limiting member, and the movable rod 3 can be connected to the limiting member in an up-and-down lifting manner. In this way, the limiting member plays a limiting role, which can limit the downward movement direction of the movable rod 3, so that the movable rod 3 can move more accurately along the direction of the valve stem 8. A further preferred technical solution is: the limiting member is a bearing 7, and the movable rod 3 can be connected to the bearing 7 in an up-and-down lifting manner. In this way, the movable rod 3 can move up and down in the bearing 7, and the bearing 7 sets a direction limit for the movable rod 3, so that the movement direction of the movable rod 3 is more accurate, and then it is pressed downward along the direction of the valve stem 8.

In this way, the left end of the fixing plate 61 is slidably connected to the slide rail, so that the online repair mechanism can be slidably connected on the slide rail with the fixing plate 61, and then real-time maintenance is performed. The left end of the mechanism connection block 62 is connected to the right end of the fixing plate 61, and the connection can also be released, which is convenient for installation and disassembly. The fixing plate 61 provides an installation position for the mechanism connection block 62, and the mechanism connection block 62 provides an installation position for the handle connection block 63 and the gas spring connection block 64. The left end of the handle connection block 63 is connected to the right end of the mechanism connection block 62, and the connection can also be released, which is convenient for installation and disassembly. The handle connection block 63 provides an installation position for the installation of the handle 1, so that the handle 1 can be rotatably connected to the handle connection block 63. The gas spring connection block 64 is connected to the lower part of the mechanism connection block 62, and the connection can also be released, which is convenient for installation and disassembly. The gas spring connection block 64 provides an installation position for the installation of the gas spring 4, so that the lower end of the gas spring 4 can be stably connected to the gas spring connection block 64. By setting the fixing plate 61, the mechanism connection block 62, the handle connection block 63 and the gas spring connection block 64, each component is easy to install and easy to replace, and the maintenance environment is improved. A further preferred technical solution is: the angle formed between the left side of the fixing plate 61 and the left side of the mechanism connection block 62 is 15°-16.5°. Thus, according to the angle design of the valve stem 8, the angle formed between the upwardly extending surface of the left side of the fixing plate 61 and the upwardly extending surface of the left side of the mechanism connecting block 62 in the repair mechanism is designed to be 15°-16.5°. When repairing the online repair mechanism, only the valve stem 8 needs to be aligned and the handle 1 is pulled down to install the locking clip, thus realizing offline auxiliary installation.
